Harmonyos Next教程
4 回复

谢谢，解决了， 原因是使用onInterceptRequest返回Raw资源时，Api9和Api11有一些区别，使用Api11的方式就好了

老哥，这是什么好意思啊，我的bugly里面全是这样的报错，一直都是webview的东西，这个怎么解决啊，好多用户在使用的出现崩溃

针对HarmonyOS鸿蒙Next Api11使用Web组件加载网页频繁崩溃并报cppcrash的问题，可能原因包括：

  1. 资源访问冲突：检查是否有多线程或异步操作同时访问Web组件资源，导致资源冲突。
  2. 内存问题：检查是否有内存泄漏或非法内存访问，这可以通过HarmonyOS的内存检测工具进行诊断。
  3. 兼容性问题：确认网页内容与鸿蒙系统的兼容性，特别是User-Agent的设置是否影响页面加载。
  4. 系统或应用bug：可能是系统或Web组件本身存在bug，建议查看HarmonyOS的更新日志和社区反馈。

如果问题依旧没法解决，请加我微信，我的微信是itying888，以便进一步分析和解决。

根据你的日志分析最后一个信息是FATAL:scoped_file.cc(43)] Check failed: . : Bad file descriptor (9)，这表明程序在scoped_file.cc文件的43行处检查文件描述符时失败了，因为文件描述符是9，而它是一个坏的文件描述符。可能的原因是文件已经被关闭或删除，但程序仍然试图对其进行操作。因此，需要检查代码中是否存在未正确关闭文件或删除文件的情况。
